Embolization is performed under local anesthesia in one day surgery unit by unilateral approach, usually the right femoral artery. Initially, pelvic angiography is performed to evaluate the iliac and prostatic arteries. Then, a 5-F catheter is introduced in right femoral artery to catheterize the left hypogastric artery and reach its anterior division. The inferior vesical artery and finally the prostatic vessels are selectively catheterized with a 3-F coaxial microcatheter. For embolization, nonspherical 100-300 μm PVA particles is used. The endpoint chosen for embolization is slow flow or near-stasis in the prostatic vessels with interruption of the arterial flow and prostatic gland opacification. When embolization of the left prostatic arteries was finished, the right prostatic arteries were embolized in the same way.
